Name That Condiment

Tonight for dinner we had cheeseburgers on the grill. I was spreading mayo on the bun, and Simon asked for "butter" on his otherwise "naked bread." He had asked for a bun...no burger or anything. I told him it wasn't butter, it was mayonnaise.

What next?

He asked for "banan-naise" on his bread. Like banana & mayonnaise. Why? I have no idea. Bananas were not a part of this meal. Funny kid.
